Shadowcat - Strength in Diversity

My first attempt at a Shadowcat/Strength in Diversity build.

Use one deck pass to set up. Prioritize getting your allies on board then Support/Upgrades (The Triskelion is the exception, we want this out asap). Once we get the Triskelion out, our fourth slot will be used to recur Nick Fury as much as possible. After that we just try to draw into and play S.i.D. We don't plan to use our Allies to chump block but most of their stats aren't incredible either, activate them if you need to ping a Tough or finish off a Scheme, otherwise just let them chill off to the side.

We always want to end our turn in Phased form to defend the Villain's activations. Thankfully S.i.D. is not an attack and we can use it when we switch after an Attack. The goal is to stay in Hero form but Phased and Confused gives you (or more likely a Teammate) a chance to flip safetly.

You have good Thwart options but this is probably the deck's weakest link. Best to chip away with basic actions, Airwalk, and E.V.A., trying to leave S.i.D.s for finishing off Villains and Minions.
